The Catholic Church has many unchangeable, general principles which do not contain exceptions. For example, divorced and (so-called) “re-married” Catholics are forbidden from receiving Holy Communion.
Pope Francis falsely teaches that all the Catholic Church’s general principles must be adapted to local circumstances and cultures. Here are his words:
[C]ultures are in fact quite diverse, and every general principle … needs to be inculturated, if it is to be respected and applied.
Quoted from Pope Francis’s apostolic constitution, Episcopalis Communio, Sept 15, 2018, §7 (ellipse is in the original; emphasis added).
 Inculturation is: “the adoption of the behavior patterns of the surrounding culture”. https://www.thefreedictionary.com/Inculturation
